New: Uber Profiler “appender only” nuget package is now available

We started to provide nuget packages for our Uber Profilers early on when nuget was available. Back then, we decided to provide you with a one click solution: you add the NHibernate Profiler (or any other of our profilers) nuget package to your project, and you can start the profiler right away. We open the profiler interface after you install the package and add some initialization code the your project to hook the profiler.

That worked great most of time, when you do a fresh installation of the profiler. But when you are doing upgrades and you do not want to use the default initialization code we provide, it can be annoying to keep removing it once you upgrade. This is way we created this issue, based on user demand.

So you can now use the NHibernateProfiler.Appender or EntityFrameworkProfiler.Appender (the same for our other profilers) package, which contains just the appender dll. No code setup and it is also a much slimmer package, so package restore will also be faster.

Use log4net version with NHibernate Profiler

We got lots of requests to support log4net when using the web.config or app.config to configure the profiler. We already supported log4net 1.2.11 if you initialized the profiler using code, eg NHibernateProfiler.Initialize(), by auto compiling our inner appedner against the version of log4net that your application is using. But when you initialize the profiler using config file you need an assembly that is already compiled against log4net.

We thought how we can support this, and we came up with an interesting solution.

Starting with build #2122, we let you call the following code from your application, which will generate an assembly that will be compiled against the version of log4net that your application is using, and will be saved to the location that you can specify in the parameter:


This will create the following dll in the output folder:


Now you can use this dll in order to initialize the profiler using the configuration file.

What’s new in Uber Prof v2.0?

Along with the launch of our new website hibernatingrhinos.com, we’re happy to announce that v2.0 of Uber Prof profilers is now in beta!

While we’re perfecting the product, you can take advantage on that and buy a license now with a 20% discount. This will work for both monthly license and standard license.

You can also request a trial license on the website, which will let you use the profiler for 30 days.

Now for the interesting staff, what’s new in Uber Prof v2.0?

1. Silverlight interface. When you run the profiler.exe the UI that opens is a OOB Silverlight application. You can also open the profiler interface in your browser, which means that you can profiler remote systems! In fact, we ported all of the WPF user interface of v1.0 to Silverlight in order to enable production profiling of remote systems.


2. Production profiling. We now supports profiling production systems, using the HibernatingRhinos.Profiler.Production.dll. If you’re using ASP.NET MVC, you will be able to configure the profiler to use the following route “/profiler” in order to see the profiler interface in your browser.


3. Performance. We tuned to performance of the profiler and the profiler now it far more responsive. You can run the profiler now for days, and it will still work.


4. Running on the cloud. We did some work in order to let you profile your application on Azure. You can profiler your cloud application right from your browser, using the production profiling feature.

The next post will contains instructions how to run the profiler in a production application, on Azure.
